Using a SpeakJet with MAVRIC or MAVRIC-II Mega128
Board

The Magnevation SpeakJet
is a voice synthesizer and complex sound synthesis chip that
accepts serial input in the form of 8-bit phoneme and sound effect
codes and coverts those to synthesized sounds. The SpeakJet can
be used to give your project speech and sound effect capability
very easily.

Here is some sample speech
output produced by the sample program's startup message below.
